Answer:

Step-by-step explanation:
We want to solve the equation:

In the interval [0, 2π).
Notice that this is in quadratic form. Namely, by letting u = sin(θ), we acquire:

Factor:

By the Zero Product Property:

Solve for each case:

Back-substitute:

Use the Unit Circle. Hence, our three solutions in the interval [0, 2π) are:

Answer:
sometimes
Step-by-step explanation:
Answer:
35d+ 32 > 25d+68
Step-by-step explanation:
Plan A: $35 a day plus a fee of $32
35d+ 32
Plan B: $25 a day plus a fee of $68
25d+68
We want to know when A costs more than B
35d+ 32 > 25d+68
Angle RQN and angle RQS, because they will add up to 180 degrees
